Judo and Aikido founders were pals in the military. Those schools were all connected at the time and were complementary. What we see today is a kind of a "commercial struggle" between different schools and martial arts for $tudents. I practiced judo and BJJ as well throughout my life, and that wasn't an issue. I see that the ideal practice for anyone could be an MMA having the self-defense and the non-competitive healthy side of things. We don't see that mindset around.
